Discussion

Entodon beyrichii is a very common species in the drier habitats of Mexico, but barely reaches the United States. The species often grows in very dry, exposed habitats and then the seta can become bleached and appear not to be red. The papillose exostome teeth and smooth to papillose endostome segments aid in identification.
